Mailadmin is a PHP-Application I created for my very first Mail-Server I had setup back in 2016 during my apprenticeship as a computer scientist specializing in system engineering. I used following tutorial: Mailserver-Anleitung von Thomas Leister.. Addidionally I used the Materiallize-CSS Framework for the design
This Mailserver setup use for the account management a easy MySQL-DB.
Recently I did a Server-Upgrade and switched to Mailcow Dockerized for my current Mailserver. I recommend it. But if you did too setup your Mail-Server with this tutorial or have another setup wich using a MySQL-DB for user management, feel free to use it. It shoud work with PHP 7.0, else feel free to update it.
You need a LAMP-Stack or equally to run Mailadmin. The PHP-Extension mysqli is needed. Additionally, I recommend you to restrict the access to the application via Apache-Authentication (.htaccess-File).
